their real structure was discernible. Subsequently I received 

 larva? and pupa3 of a second species of South African 

 Blepharocerida?, and when, acting on a suggestion made to 

 me by Mr. H. Scott, I dissected out imagos from the pupa? 

 of this form and of K. barnardi, I found that here again the 

 eyes were of the same type, though there were extremely 

 interesting differences between the two forms which will be 

 described below. It thus appears that these South African 

 species form to some extent a connecting-link between the 

 South American Kelloggina and the European Apistomyia, 

 resembling the former in wing-venation and the latter in 

 the structure of the eyes. Dr. A. Lutz informs me that he 

 has recently obtained both sexes of a species of true Kellog- 

 qina in Brazil, and that in both males and females the eyes 

 are simple. As the condition of the eyes is (doubtless 

 correctly) regarded as a character of generic importance in 

 this family of flies, it becomes necessary to form a new genus 

 for K. barnardi and the new species referred to. I propose 

 the term Elporia*, which may be defined as follows: — 



Elporia, gen. nov. 



Imago : Eyes dichoptic, hairy, divided by a horizontal 

 band into two distinct parts. Antennae 14- or 15-jointed. 

 Mouth-parts similar in the two sexes; mandibles absent; 

 maxillse well developed, but without cutting-teeth, as long 

 as the first joint of the palpi ; palpi three- or four-jointed, 

 longer than the proboscis by fully the length of the last 

 joint; first joint longer than the others. Proboscis as long 

 as or longer than the vertical diameter of the head. Wing- 

 venation as in Paltostoma. Front and middle tibia? without 

 spurs, hind tibia? with one large spur. Last tarsal joint 

 without any group of spines at the base. Claws usually 

 elongate, with several spines on the underside, sometimes 

 partly pulvilliform. 



Pupa: Integument smooth; respiratory horns each com- 

 posed of four flattened lamella?, the two inner much narrower 

 and rather shorter than the two outer. 



Larva : Antenna? rather short, two-jointed. Integument 

 provided with more or less distinct short spines, the largest 

 of which are arranged in a definite way, two occurring near 

 the anterior border, four near the posterior border, and one 

 at each side of each of the five intermediate segments. Six 

 pairs of hairy lateral processes. Five pairs of gill-tufts, each 



* From eKitwpri, hope.
